Delve into the intricacies of reviewing P1 parking plumbing drawings, understanding the importance of mapping out lines, and recognizing the connection between different sheets. This article walks you through the key features of these drawings, from sanitation and storm drain lines to fire protection and hot water lines, highlighting the careful attention to detail required.
Key Insights
- The P1 parking plumbing drawings detail the layout of plumbing lines on a specific level, providing essential information like sanitation and storm drain lines and their connections to other areas.
- Not only do these drawings indicate where certain lines are located, but they also provide crucial safety instructions, such as avoiding routing piping over electrical rooms due to the hazardous combination of electricity and water.
- The drawings also label and identify different types of lines, such as hot water return lines, gas lines, and fire standpipes. They further illustrate the need for meticulous attention to detail, particularly in referring to the legend for accurate identification of the various water lines.

Let's begin our review of the P1 parking plumbing drawings. Now picture yourself being on the level P1. These plumbing lines would be the lines that you would see in the ceiling above you.
We can see that we have a keynotes legend, and there are a few general notes. I'd like to pan down to the bottom and discuss this first. You can see that it says a four-inch sanitation line down and then a storm drain down.
I'm going to flip over to the underground plumbing drawing. In the underground drawing, you can see that it's showing a four-inch sanitary line from the floor above and the storm line from above as well. So what's happening is in the P1 drawing, we have the lines coming down adjacent to the column.
One is feeding into the sanitary, the other is feeding into the storm line. So you can start to see that there's a relationship between the different sheets. So I'm going to now return back to our other drawing.
We're back in the P1 drawing. We've just discussed this area. You can see that there are notes for a fire protection dry standpipe with a two-and-a-half-inch hose connection at this egress area.

You'll see the same thing happening here. As we pan around, you'll see notes that are calling out what's happening here with the piping. Please pay attention to this.
This is the electrical room, and it specifically says, "Do not route piping over electrical rooms." Electricity and water don't mix. So they're taking every possible precaution.
If I pan here, you'll start to notice that there is a massive number of pipes in this area. So again, I'd like to encourage you to go back to the legend on the first of the plumbing pages to identify what kind of pipes they are. They have done an excellent job labeling things, though.
You can see that they're calling out two 165-degree hot water and hot water return lines, 140-degree hot water, hot water return, and 120-degree hot water and hot water return. You'll notice that there are shutoff valves at the end of the lines. There are keynotes.
Again, they're continuing the labeling of the hot water and hot water return lines here, just to make sure that people don't get confused. These will be feeding up to the kitchen area. Then we have lines that go into the bathrooms.
There are some gas lines that go to the dryers upstairs. And again, a note for a fire standpipe system. There are notes up here for storm drains.
And you can see that there's a capped sanitary line for the future restaurant above. Again, an excellent drawing. It simply requires close attention to detail and frequent reference to the legend to ensure that you understand which of these water lines is being presented.
Let's go on to our next sheet.
